Abstract

A headrest assembly (36) for a vehicle seat (10) and a method of installation. The headrest assembly (36) includes a support post (28) pivotally connected to an installation post (16) via an installation hinge (30). The installation post (16) is installed into a guide sleeve (14) of the seat back (12) such that the installation hinge (30) is still exposed, allowing the headrest body (34) to tip down and forward. The seat (10) is then installed into the vehicle body (50), after which, the headrest body (34) is tipped up and pushed down until a support post notch (38) engages with an installation catch (20) mounted on the guide sleeve (14). The headrest (36) will now remain in its use position with the hinge (30) contained within the guide sleeve (14).

Claims

1. A seat for a vehicle comprising:

a seat back portion that is adapted to mount generally vertically in the vehicle, with the seat back portion including a head rest support receiver having a removal limiter; and

a headrest including a main body;

an installation post having a first end received within the support receiver, and a second end, disposed opposite to the first end, having a hinge receiving portion; and

a support post having a first end securely connected to the main body, a second end, disposed opposite to the first end, having a hinge portion pivotally connected to the hinge receiving portion, and a first engagement device engageable with the removal limiter when the hinge portion is received within the support receiver.

2. The seat of claim 1 wherein the installation post further includes a second engagement device for engaging with the removal limiter and retaining the installation post once installed partially into the support receiver.

3. The seat of claim 2 wherein the support receiver is a guide sleeve, and the installation post and support post are telescopically received within the guide sleeve.

4. The seat of claim 3 wherein the removal limiter is an installation catch having a catch flange and a catch release, and the first engagement device is an installation notch, with the catch flange received within the installation notch.

5. The seat of claim 4 wherein the catch release couples to the catch flange or removing the catch flange from the installation notch.

6. The seat of claim 1 wherein the installation post is made of plastic and the support post is made of metal.

7. The seat of claim 1 further including an installation hinge screw pivotally coupled to the hinge portion and the hinge receiving portion.

8. A headrest for a vehicle seat having a seat back and a support receiver with a removal limiter, the headrest comprising:

a main body adapted for receiving a head of a vehicle occupant;

an installation post having a first end adapted to be received within the support receiver, and a second end, disposed opposite to the first end, having a hinge receiving portion; and

a support post having a first end securely connected to the main body, a second end, disposed opposite to the first end, having a hinge portion pivotally connected to the hinge receiving portion, and a first engagement device adapted to engage with the removal limiter when the hinge portion is received within the support receiver.

9. The headrest of claim 8 wherein the installation post further includes a second engagement device adapted for engaging with the removal limiter and retaining the installation post once installed partially into the support receiver.

10. The headrest of claim 9 wherein the support receiver is a guide sleeve, and the installation post and support post are adapted to be telescopically received within the guide sleeve.

11. A method for installing a seat and headrest into a vehicle, with the seat having a seat back portion that includes a support receiver and a removal limiter, and the headrest having a main body;

an installation post having a first end received within the support receiver, and a second end, disposed opposite to the first end, having a hinge receiving portion; and

a support post having a first end securely connected to the main body, a second end, disposed opposite to the first end, having a hinge portion pivotally connected to the hinge receiving portion, and a first engagement device engageable with the removal limiter when the hinge portion is received within the support receiver;

the method comprising the steps of;

hingedly connecting a headrest support post to a headrest installation post;

installing the installation post partially within the support receiver of the seat back prior to installation of the seat into the vehicle;

installing the seat into the vehicle; and

after installation of the seat into the vehicle, manipulating the headrest to cause the support post to partially insert within the support receiver such that the removal limiter engages the first engagement device.

12. The method of claim 11 wherein the headrest installation post further includes a second engagement device for engaging with the removal limiter and retaining the installation post once installed partially into the support receiver, with the step of installing the installation post comprising:

installing the installation post partially within the support receiver such that the removal limiter engages the second engagement device.
